Last year, a friend bought a Ford Pickup with a 300 six. Soon after warm-up, the temp gage went to full hot! He had been going through every idea he could come up with, like new radiator, shroud, cap, water pump, thermostat, timing, etc, etc. The gage showed it was still running hot, although it ran and idled well.
I installed a mechanical Stewart-Warner gage and it indicated much lower temp than the factory unit did. The gage is sometimes the last thing folks look at! Who woulda thunk it?
